It is difficult to get the big picture regarding clergy abuse in the Roman Catholic Church, for a number of reasons. One is that the Church - and, unfortunately, its abusing priests - are spread all over the world. Another is that the Church is organized in dioceses, which tend to be city-specific. A third is that the organization reports in a hierarchical fashion, toward Rome. And a fourth, and final reason is that the Church prizes secrecy and avidly resists accountability to civil authorities.
